| 英文摘要 | We invert s-wave velocities for the 3d upper-mantle temperatures, in which the position with a temperature crossing the 1300 degrees c adiabat is corresponding to the top of the seismic low velocity zone. the temperatures down to the depth of 80 km are then calculated by solving steady-state thermal conduction equation with the constraints of the inverted upper-mantle temperatures and the surface temperatures, and then surface heat flows are calculated from the crustal temperatures. the misfit between the calculated and observed surface heat flow is smaller than 20% for most regions. the result shows that, at a depth of 25 km, the crustal temperature of eastern china (500-600 degrees c) is higher than that of western china (< 500 degrees c). at a depth of 100 km, temperatures beneath eastern and southeastern china are higher than the adiabatic temperature of 1300 degrees c, while that beneath west china is lower. the tarim, craton and the sichuan basin show generally low temperature. at a depth of 150 km, temperatures beneath south china, eastern yangtze craton, north china craton and around the qiangtang terrane are higher than the adiabatic temperature of 1300 degrees c, but is the lowest beneath the sichuan basin and the regions near the indian-eurasian collision zone. at a depth of 200 km, very low temperature occurs beneath the qinghai-tibet plateau and the south to the tarim craton. |
